hi:
this problem is a very little problem of jbpm-server.
the problem is what when the processdefinition contains superstates with nodes inside, the processimage.jpg don't reflect these internal nodes, and when the jbpm try to find an image that reflect the internal node launch a nullpointerexception.
i found a really cool patch to that problem searching in the forum.
it was really simple: replace the reference to the image with a static image ( in that case, with an image of aria giovanni 8P'''' , Cool eh?? ).
Thanks anyway
